SPECIFICATION forming part 0f Letters :Patent N0. 707,504, dated August19, 1902.

Application filed June 7, 1900.

To a/ZZ whom t 72u03/ concern:

Be it known that I, WILLIAM B. H. DowsE, of Newton, in the county ofMiddlesex and State of Massachusetts, have invented a new and usefulImprovement in Fasteners, of which the following, taken in connectionwith the accompanying drawings, is a specification.

My invention 'consists of a new and improved snap-fastener and themembers thereof, which consist of a socket and stud, one at least ofthese members being resilient, so as to operate in the usual manner.

In the drawings which accompany this specification an embodiment of myinvention is illustrated.

Figure l shows the two parts of the socket member in readiness forattachment to the material of the glove or other garment on which thefastener is to be used. Fig. 2 shows the socket member attached to thematerial. Fig. 3 showsthe two parts of the stud member in readiness forattachment, and Fig. 4 the stud attached to-the material.

The socket member of the fastener (shown in Figs. l and 2) consists of acap b, having a downturned flange c, which may be rolled or turned atits edge c', so as to present a smooth surface to the material, and astud-receiving collar, which comprises the stud-opening CZ, the lip e,flange f, edge g, (which may be rolled over to secure a smooth surface,)and, if the socket member is to supply the required resiliency, theslits or openings h. The socket member is attached to the material byfitting the cap and stud-receiving collar together, with the materialbetween them, the flange c of the cap having an internal diametersufiicient for the purpose. Then by means of a suitable tool or pressthe flange c is crimped or rolled under the edge g of the liange f,confining the material and securely joining the two parts of the socketmember. The lip c and flange f are proportioned so that sufficient spaceis left above the opening d for the entry of the stud. (Shown in Figs. 3and 4.)

The stud member (shown in Figs. 3 and 4) consists of two parts, a ring5, rolled or rounded, so as to present a smooth surface, and the stud,which comprises the central Serial No. 191372. (No model.)

crown l, the constricted neck 2, the shoulder 3, and flange 4. Theflange 4 is preferably a little contracted at its mouth, presenting aconical rather than a cylindrical surface, although a plain cylindricalflange may be made to serve. The ring 5 I prefer to construct by rollingover a ring or band of sheet metal, so that in effect it is an annulartube, slightly flattened, with themeeting edges of the tube on theoutside of the ring, and thereby forming a split tubular ring. Thisconstruction insures a smooth and unbroken surface and guards againstabrasion of the fabric or material a. The stud member is attached asfollows: The stud part and ring are put together on opposite sides ofthe material a, the ring 5 embracing the flange 4 and the materialbetween. Then by means of a suitable tool or press the flange 4 isexpanded under the ring and the edge of the shoulder 3 pressed down uponthe ring, confining the material between the two pieces. As shown, boththe cap and the collar are provided with an inturned portion at thepoints where the greatest strain is presented-viz. ,at the points c andg, where the edges oppose each other. This construction not onlypresents a smooth face to the material, as above pointed out, but alsoacts as a reinforce to prevent either or both of the opposing edgesunder pressure from moving in a direction which would permit of aseparation of the parts or a redliction of the stretched condition ofthe material between the parts. The stud of Figs. 3 and 4 is shown asnon-resilient and the socket of Figs. l and 2 as resilient. Thesecharacteristics are interchangeable, as is well known.

I claim- 1. A stud member of a snap-fastener consisting of a ring, ahollow 'stud having a central crown, a neck below the crown, a shoulderand depending flange, the depending flange lying within the ring, andseparated therefrom by the material to which the stud member isattached, the edge of the flange being turned outward so that the ringis held between the outward-turned edge of the flange and shoulder,substantially as shown and described.

2. A stud member of a snap-fastener consisting of a ring, a hollow studhaving a oen-- IOO tral crown, a neck below the crown, a shoulder anddepending flange, the flange lying within the ring and separatedtherefrom by an imperforate flexible material to which the stud memberis attached, the flange being turned outward and the shoulder crusheddownward, so as to bind the ring and confined material between theoutwardly-turned edge of the flange and the shoulder, substantially asshown and described.

3. Asnap-fastener consisting ofastud member and a socket member adaptedto mutual engagement, the stud member consisting of a ring, a hollowstud having a central crown a neck below the crown, a shoulder anddepending flange, the depending flange lying within the ring, andseparated therefrom by the material to which the stud member isattached, the edge of the flange being turned outward so that the ringis held between the outward-turned edge of the flange and shoulder, andthe socket member consisting of a cap, a stud-engaging collar lyingwithin the cap, and separated therefrom by the material to which thesocket member is attached, the edge of the cap being turned under theedge of the collar, and the material conned thereby, substantially asshown and described.

4. A stud member of a snap-fastener consisting of a tubular ring, ahollow stud having a central crown, a neck below the crown, a shoulderand depending flange, the depending flange lying within the ring, andseparated therefrom by the material to which the stud member isattached, the edge of the flange being turned outward so that the ringis held between the outward-turned edge of the flange and shoulder,substantially as shown and described.

5. A stud member of a snap-fastener consisting of a split tubular ring,a hollow stud flange being turned outward so that the ring is heldbetween the outward-turned edge of the flange and shoulder,substantially as shown and described.

(i. A stud member of a snap-fastener consisting of a tubular ring, ahollow stud having a central crown, a neck below the crown, a shoulderand depending flange, the flange lying within the ring and separatedtherefrom by an imperforate flexible material to which the stud memberis attached, the flange being turned outward, and the shoulder crusheddownward, so as to bind the ring and confined material between theoutwardly-turned edge of the flange and the shoulder, substantially asshown and described.

7. A stud member of a snap-fastener consisting of a split tubular ring,a hollow stud having a central crown, a neck below the crown, a shoulderand depending flange, the flange lying within the ring and separatedtherefrom by an imperforate flexible material to which the stud memberis attached, the flange being turned outward, and the shoulder crusheddownward, so as to bind the ring and confined material between theoutwardlyturned edge of the flange and the shoulder,

substantially as shown and described.

In testimony whereof I have signed my name to this specification, in thepresence of two subscribing witnesses, on this 4th day of June, A. D.1900.
